Introduction

Low Cost 3-Axis MEMS Gyro

Introduction
The ER-3MG-12 Low Cost 3-Axis MEMS Gyro has small volume, light weight, simple structure and good reliability. The biggest function of the three-axis gyroscope is to “measure the angular velocity to judge the motion state of the object, so it is also called a motion sensor”. In other words, this thing can let our equipment know where we are and where we are going. ”

Applications
Integrated Navigation Systems & Inertial Guidance System
Flight Control & Guidance System
Attitude Heading Reference Systems (AHRS)
Stabilization of Antennas, Cameras & Platforms
